Krystal upgrades to a $2.79 shake

CHATTANOOGA Tenn. Krystal, the regional burger chain, is upgrading its milkshakes with the rollout of MilkQuakes, a line of the frozen drinks custom-made with real ice cream and milk. Each sells for $2.79.

The new treats will be offered in vanilla, strawberry and chocolate versions. Each is topped with a optional dollop of whipped cream and served in a 20 oz. cup.

Krystal isn't the only chain hoping to get some dollars from ice cream: Last week struggling Krispy Kreme Doughnuts Inc. said it was testing a line of ice cream desserts at a unit in Winston-Salem, N.C.

Acoupon for a free MilkQuake will be distributed via email and posted on the company's official MySpace page at

The brand's franchisor, The Krystal Co., owns or franchises more than 400 restaurants in 12 Southeastern states.
